The ML isnt denying relationships or labels or his feelings. He clearly recognizes them(noting how attached they are), how much he cares for Kyuho, and how these things usually evolve into dating(thats why he finally brought it up in this last chapter). But note the passing bus comment.
His overriding concern is that if they ever break up, their relationship will sour until they're completely cut off from one another. At this point, he'd rather stay platonic than potentially lose Kyuho. BUT what the ML is completely overlooking, is that he could lose Kyuho anyways as friends. Even platonic relationships could go bad, and someone else could come along and become a much bigger part of Kyuho's life.

he does actually not really believe in love or relationships! it gets touched on in a chapter that hasn’t been translated yet, so i won’t elaborate, but he’s genuinely pretty uninterested in the idea of love even if he recognises that things like how they interact are often linked to dating. but yeah, his main concern really is just his prioritising their platonic relationship over the idea of a romantic one!! it really is that like… to him, kyuho being His Person (platonic intended) is the most important thing above all else and that approaching their relationship from any other angle would rock the boat and potentially shatter that, without realising that by drawing this line without looking into it or his feelings any further he’s putting their platonic relationship at further risk. well-put post!

Actually did not expect this. Progress for both characters has officially stalled or gone backwards. I hate that JJK is now well-aware of Kim Dan's health condition and still proceeds, aggressively too. I also hate that Kim Dan refuses to get better, and is even disregarding his doctor's advice. ironic for someone in the medical field.
The fact that JJK even urged him to keep going when Kim Dan was passing out rly says to me that he doesn't see him as an actual person yet. And Kim Dan really needs to get it together. Like bro, you're an adult with stable finances, a happy grandma, no one blames you, and hot dude is serving himself up as FWB.
MAYBE Seo-In did kiss the brother, to make the MC jealous. Honestly, he's just a little unhinged enough and petty enough. I'm realizing that now with the recent chapters.
